Bottle

ABSTRACT

Disclosed is a bottle for containing liquid contents including a body portion, at least part or the entire portion of an upper portion of which is provided with a plurality of guides which protrudes inward from an inside surface thereof and is in a spiral pattern so that the liquid contents can be guided towards an opening of a neck portion of the bottle while spirally revolving inside the bottle.

TECHNICAL FIELD

The present invention relates to a bottle for containing liquid contents therein, and more particularly to a bottle which can stably discharge liquid contents through an opening by making the contained liquid contents smoothly flow along a plurality of guides arranged in a spiral pattern.

BACKGROUND ART

At present, beverages, such as water and colas, liquors, or liquid-type food, are contained in various kinds of containers. Examples of such liquid containers are paper bottles, PET bottles, glass bottles, and metal bottles (aluminum cans).

Of these containers, the PET bottle is the most popular liquid container thanks to its many advantages, such as that it can contain contents for a relatively long time, i.e. contents in the PET bottle barely decay after a long time of storage because gas transmittance of the PET bottle is very low compared with other kinds of containers, it hardly breaks when it is dropped in a state in which it is filled with contents, it does not produce broken pieces even when it is ruptured, and it is convenient to carry and keep the PET bottle because the PET bottle is lighter than a glass bottle.

The known PET bottle having the above advantages is generally composed of a neck portion which has an opening at an end and threads on an outer surface thereof for sealing when the neck portion is combined with a cover, and a body portion extending from the neck portion and containing contents therein. The body portion may be of various sizes and forms according to the type of contents.

DISCLOSURE Technical Problem

There are ways of discharging the contents of the PET bottle. For example, when a user tilts the PET bottle to pour the contents into a vessel, such as a cup, or to directly drink the contents from the PET bottle, the contents are discharged from the PET bottle.

In such a case, there is a possibility that the contents contained in the body portion of the PET bottle are not smoothly discharged but are abruptly discharged at excessive pressure, so that the contents are likely to gush out of the PET bottle and to splatter on a user's clothes or the surrounding area.

In particular, when the user directly drinks the contents from the bottle, the user may choke or his or her clothes or body may get splashed.

Further, since the bottles have large volumes even when they are empty, it is difficult to deal with the empty bottles or it is required to install additional equipment in households to reduce the volume of the empty bottles.

Technical Solution

In order to accomplish the above and other advantages, there is provided a bottle for containing liquid contents including a body portion, at least part or the entire portion of an upper portion of which is provided with a plurality of guides which protrudes inward from an inside surface of the body portion in a spiral pattern so that the liquid contents can be guided toward an opening of a neck portion of the bottle while spirally revolving inside the bottle.

It is preferable that the entire body portion of the bottle be provided with the plurality of guides which protrudes inward from the inside surface of the bottle in a spiral pattern.

It is preferable that a section of each of the plurality of guides have a shape of the letter “C”?or a reversed letter “C”?when each guide is cut across its width, and a curvature of each guide be uniform over a portion of its length or change in a manner such that a curve of a leading portion is relatively gentle and a curve of a back portion is relatively tight.

It is preferable that the plurality of guide lines be four or eight lines of spiral patterns.

It is preferable that the bottle be a paper bottle, a PET bottle, a metal bottle, or a glass bottle.

It is preferable that each of the plurality of guides take a form in which a width of a lower portion is larger than that of an upper portion.

It is preferable that each of the plurality of guides have a uniform width at the upper portion and the lower portion.

As described above, according to the invention, the bottle is provided with a plurality of guides having a spiral pattern winding around the body portion of the bottle so that liquid contents in the bottle can be stably guided toward and discharged through the opening of the bottle while spirally revolving inside the bottle. Since the abrupt gushing of the liquid content is prevented, it is possible to safely pour and drive the liquid contents from the bottle and to prevent splattering of the liquid contents attributable to the abrupt discharge of the liquid contents from occurring.

In the case in which the bottle is used to contain a beverage, such as water, cola, or juice, since the flow of the beverage is moderate, it is possible to prevent accidents such as the user choking.

In the case in which the bottle is a PET bottle, it is possible to reduce the volume of the empty bottle by applying external force to the empty bottle after the contents have been emptied so that the bottle is twisted as the plurality of guides is compressed. Accordingly, it is easy to dispose and recover the empty bottles.

Advantageous Effects

It is an advantage of some aspects of the invention that a bottle is provided with a body provided with a plurality of guides arranged in a spiral pattern so that liquid contents can be smoothly and stably discharged through an opening of the bottle, while spirally revolving inside the bottle.

It is another advantage of some aspects of the invention to provide a bottle which can prevent liquid contents from gushing out of the bottle so that a user can safely pour or drink the liquid contents, and it is possible to prevent contamination attributable to a violent gushing of the liquid contents from occurring.

It is a further advantage of some aspects of the invention to provide a bottle provided with a body which can be easily twisted by external force when all of the contents have been emptied, so that the volume of the bottle is reduced to the maximum.

BEST MODE

Reference will now be made in greater detail to exemplary embodiments of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.

Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings through which like elements are referenced by like numbers. In describing the invention, details on the structure or function of related arts are omitted if they may obscure the subject of the invention.

Terms in the description are defined considering functions of elements of the invention, so that the terms must be construed with reference to the contents of the present specification as a whole because such terms can be differently defined according to the intents of people skilled in their arts or customs.

FIG. 1 is a perspective view illustrating a bottle according to one embodiment of the invention, FIGS. 2A and 2B are sectional views illustrating a section of the bottle taken along line II-II of FIG. 1, FIG. 3 is a perspective view illustrating a bottle according to another embodiment of the invention, and FIGS. 4A and 4B are sectional views illustrating a section of the bottle taken along line IV-IV.

As shown in FIGS. 1 to 3, the bottle of the invention includes a neck portion 110 and a body portion 120.

The neck portion 110 has an opening 111 and a thread 112 to be combined with a cover 113 in a screwed manner. Alternatively, the neck portion may be combined with the cover 113 in manners different from the screwed manner for ensuring sealing of the bottle. For example, the cover 113 can be attached to or detached from the neck portion 110.

The body portion 120 extends from the neck portion 110 and contains liquid contents therein.

The bottle 100 having the above-mentioned structure can contain a beverage, such as water or cola, a liquor, a saline solution, or a liquid-type food, and may be made of various materials.

The bottle 100 may be a paper bottle, a PET bottle, a metal bottle, or a glass bottle.

According to the preferred embodiment of the invention, the bottle 100 may be a polyethylene terephthalate resin (PET) bottle.

As shown in FIGS. 1 to 3, the body portion 120 takes a form in which a plurality of guides 121 is provided in a spiral pattern and protrude inward from the inside surface of the entire or part of an upper portion of the body portion 120 which is on the upper side of the middle of the body portion 120 in a length direction so that the liquid contents proceed toward the opening 111 of the neck portion 110 while spirally revolving inside the bottle 100 and are then discharged out of the bottle 100.

With such a structure, the outer surface of the body portion 120 with the plurality of guides 121 is depressed in the form corresponding to the plurality of guides 121.

As the plurality of guides 121 is provided to the upper portion of the body portion 120 in the spiral pattern, the body portion 120 is wavelike in appearance.

Further, a sectional view of the body portion 120 shows that each of the plurality of guides 121 has the shape of a letter “C”?or a reversed letter “C”.? When the section of the body portion 120 is viewed in the direction in which the contents proceed, the curvature of a leading portion is relatively loose but the curvature of the back portion is relatively tight.

Alternatively, the body portion may take a form in which the curvature is maintained constant.

When the liquid flows in the above-mentioned manner, the curvature of a portion with which the liquid makes earlier contact must be relatively loose and the curvature of a portion to which the liquid contacts later must be relatively tight. The portion having the relatively tight curvature hinders the flow of the liquid primarily and than the portion having the relatively loose curvature makes the flow of the liquid slower. The border between the portion with the relatively tight curvature and the portion with the relatively loose curvature takes a streamlined shape so that the friction with the liquid is reduced.

In the case in which the curvature is constant at every portion, it is also possible to attain the same advantage of controlling the speed of flow of the liquid in the above-mentioned manner.

It is preferable that the plurality of guides 121 take a form composed of four or eight spiral lines, but the form is not limited thereto. That is, the form may be composed of other than eight spiral lines. Further, the widths of the plurality of guides 121 are narrower at a relatively upper area and broader at a relatively lower area.

The widths of the plurality of guides 121 gradually decrease toward the upper area and increase toward the lower area, but do not change from a midpoint to the bottom of the body portion in length.

Alternatively, the widths of the guides 121 may be uniform over their lengths.

FIG. 1 shows the PET bottle 10 having the above-described structure. In FIG. 1, the widths of the plurality of guides 121 in a spiral pattern are uniform over their lengths. FIGS. 2A and 2B are plan views of the upper part of the body portion of the PET bottle 100, which are taken along II-II of FIG. 1 and viewed from the bottom side. FIG. 2A shows the case in which the number of guides of the plurality of guides 121 is eight, and FIG. 2B shows the case in which the number of guides of the plurality of guides 121 is four.

FIG. 3 shows the PET bottle 100 having a form in which the widths of the plurality of guides 121 decrease toward the upper end but are gradually increased toward the middle point of the bottle from which the widths are uniform. FIGS. 4A and 4B are plan views taken along line IV-IV of FIG. 3 and viewed from the bottom side of the PET bottle 100.

FIG. 4A shows the case in which the number of guides of the plurality of guides 121 is eight and FIG. 4B shows the case in which the number of guides of the plurality of guides 121 is four.

FIG. 5 is a perspective view illustrating a PET bottle according to another embodiment of the invention.

As shown in FIG. 5, the PET bottle 100 according to this embodiment of the invention basically is similar in form and function to the PET bottle shown through FIGS. 1 to 4B. Accordingly, repetitive description will be omitted and only the differences therebetween will be described.

As shown in FIG. 5, the entire body portion 120 of the PET bottle 100 has a plurality of guides 121 protruding inward from the inside surface of the body and making a spiral pattern.

Accordingly, the entire body portion 120 is wavelike in appearance. FIG. 6 is a perspective view and a section-enlarged view illustrating the PET bottle 100 and for explaining the curvature of the guides 121 provided to the PET bottle 100.

As shown in FIG. 6, when tilting and pouring the liquid contents, for example cola, in the PET bottle 100, the liquid contents revolve along the plurality of guides 121 inside the PET bottle 100 and therefore the liquid contents are discharged with uniform flow through the opening 111.

As shown in FIG. 6, a curvature of a portion (b) of each guide 121 which is on the leading side of a midpoint (c) in the direction of the liquid contents flowing out is tighter than a curvature of a portion (a) which is on the back side of the center (c). That is, the portion (a) has a gentle curve and the portion (b) has a tight curve. As a result, this form prevents the liquid from being abruptly discharged. FIG. 7 is a comparative view for illustrating a procedure of disposing of the PET bottle according to the embodiment of the invention.

The PET bottle 100 is crushed and distorted by twisting and compressing along the plurality of guides 121 formed in the body portion 120 of the PET bottle 100. When a compressing force is applied to the PET bottle 100, the middle point or a border between the large-curvature portion and the small-curvature portion of each guide 121 having the letter “C” shape or the reversed letter “C” shape is folded over a portion of the length of the spiral pattern, so it is possible to reduce the volume of empty bottles.

For this reason, it is possible to make recovering empty bottles easier.

Although the bottle of the invention has been described in terms of preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations may be made without departing from the spirit of the invention. Thus, the scope of the invention must be defined by the appended claims and it is intended that the present invention covers the modifications and variations of this invention.
